Abstract
A thermosetting adhesive composition based on condensed tannins comprises a hardening agent selected from the group which consists of: A) products of the reaction of a nitroparaffin with formaldehyde in an alkaline medium, of the general formula: <CHEM> in which R1 and R2 are selected, independently of one another, from C1-C4 alkyl and C1-C4 hydroxyalkyl groups; B) water-miscible urea-formaldehyde and melamine-formaldehyde condensation products with degrees of polymerization no greater than 4; C) products of the reaction of formaldehyde, in a basic medium, with urea-carbohydrate adducts, the adducts being products of the reaction of urea with a carbohydrate in an anhydrous medium, in the fused state.
